[0024] It should be noted that, in the absence of conflict, the embodiments in the present application and the features described in the embodiments may be combined with each other. The present application is further described in detail below in conjunction with the drawings and specific embodiments.

[0025] As attached Figure 1 To Attachment Figure 4As shown, a lamp with a conveniently detachable light shield comprises a lamp housing 1 and a light shield 2 detachably connected to the lamp housing 1, wherein the lamp housing 1 is provided with a slot 11 extending along its length and having an opening, the opening being used for the light shield 2 to extend out, the light shield 2 is provided with a clip 21 extending along its length, a slot 111 communicating with the slot 11 is provided at the end of the lamp housing 1 in the length direction, and the clip 21 on the light shield 2 is plugged into the slot 111. To the slot 11, an end cover 3 is fixedly provided on the end of the lamp housing 1, and a sliding member 4 is slidably provided on the end cover 3, and the sliding member 4 has a stop portion 41 and a passing portion 42. When the stop portion 41 of the sliding member 4 slides to a position opposite to the slot 111, the stop portion 41 can prevent the card strip 21 from sliding out of the slot 111, and when the passing portion 42 of the end cover 3 slides to a position opposite to the slot 111, the passing portion 42 can allow the card strip 21 to slide out of the slot 111. Specifically, the through portion 42 is a "C"-shaped notch groove, and the stopper portion 41 is an "L"-shaped protrusion; when the "C"-shaped notch groove slides to correspond to the position of the notch 111, the card strip 21 can be inserted into the card slot 11 from the "C"-shaped notch groove and the notch 111, or the card strip 21 can be pulled out from the card slot 11 through the notch 111 and the "C"-shaped notch groove, so as to realize the disassembly or installation of the light shielding plate 2; if the light shielding plate 2 is installed, the "L"-shaped protrusion can be slid to the position opposite to the notch 111, and at this time, the "L"-shaped protrusion can prevent the card strip 21 from sliding out of the notch 111. Compared with the prior art, the light shielding plate disassembly and assembly structure created by the present invention does not require the aid of tools, and the light shielding plate can be quickly disassembled and assembled manually, which greatly facilitates the assembly process of the product.

[0026] As attached Figure 5 As shown, a return spring 5 is provided between the end cover 3 and the sliding member 4 , and the return spring 5 acts on the sliding member 4 to return to its original position after sliding, so that the stopper 41 and the notch 111 remain in relative positions.

[0027] As attached Figure 1 To Attachment Figure 3 As shown, the end cover 3 is provided with a guide groove 31, and the sliding member 4 is slidably adapted in the guide groove 31. The sliding member 4 is provided with at least two limiting holes 43, and the limiting holes 43 are gap-fitted with fixing members 6. The fixing member 6 passes through the limiting holes 43 and is connected to the end cover 3. The limiting holes 43 are strip-shaped countersunk holes, and the type of the countersunk holes is a cylindrical countersunk hole. The fixing member 6 is a screw, and the threaded portion of the screw is adapted to the minimum aperture of the countersunk hole, and the nut portion is adapted to the maximum aperture of the countersunk hole, so that the sliding member 4 slides back and forth in the limiting space of the countersunk hole.

[0028] As attached Figure 1As shown, at least two protruding guide columns 32 are provided on the end cover 3 and located in the guide groove 31, and a first groove 44 corresponding to the guide column 32 is provided on the sliding member 4. The guide column 32 is slidably adapted to the first groove 44, so that the sliding member 4 can be guided to slide smoothly.

[0029] As attached Figure 5 As shown, a second groove 33 is provided on the end cover 3 and directly below the guide column 32. The first groove 44 and the second groove 33 are combined to form a receiving groove 100 for accommodating the reset spring 5. One end of the reset spring 5 abuts against the receiving groove 100, and the other end abuts against the guide column 32. In addition to playing a guiding role, the first groove 44 can also be combined with the second groove 33 to form a receiving space for accommodating the reset spring 5, so that the sliding member 4 has elastic force to facilitate the reset action.

[0030] As attached Figure 6 As shown, the stopper 41 is an "L"-shaped protrusion so as to form a notch 411, and the end cover 3 is provided with a positioning protrusion 34. During the sliding process of the sliding member 4, the notch 411 can be matched with the positioning protrusion 34, so as to prevent the sliding member 4 from deviating during the sliding process, and to correct the positioning of the sliding member 4 after the deviation occurs.

[0031] As attached Figure 6 As shown, at least two guide blocks 36 are provided at the bottom of the end cover 3, and the bottom of the sliding member 4 is provided with recesses 45 corresponding to the guide blocks 36 one by one. The guide blocks 36 and the recesses 45 slide in cooperation with each other to further play a guiding role.

[0032] As attached Figure 1 As shown, a positioning member 7 is provided between the end of the lamp housing 1 and the end cover 3, and the positioning member 7 includes a plug-in block 71 and a positioning pin 72 slidably provided on the plug-in block 71. The end of the lamp housing 1 is provided with a plug-in slot 101, and the end cover 3 is provided with a positioning hole 35. The plug-in block 71 is plugged into the plug-in slot 101, and the positioning pin 72 can slide through the positioning hole 35 to extend out of the end cover 3 or slide back into the positioning hole 35. During installation, the plug-in block 71 can be fixedly connected to the end cover 3 first, and then the plug-in block 71 can be plugged into the plug-in slot 101, and finally the end of the end cover 3 and the lamp housing 1 can be fixedly connected; when the positioning pin 72 slides through the positioning hole 35 and extends out of the end cover 3, the positioning pin 72 can be inserted into another positioning hole 35 adjacent to it, thereby completing the positioning assembly between adjacent lamp housings 1.

[0033] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various equivalent changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
